In a study done this year, only 4 people out of 761 had painful urination. That doesn't mean that you are not one of that small minority, but maybe you have a urinary tract infection and need antibiotics.
I was fine the first 3 days on this and then I started to feel the pain last night. Also, I would think with this much PPI I should not have reflux, but today has been a disaster. I am going to give it one more day
